Ferns are the most abundant group of
seedless vascular plants, with about
12,000 living species. Recent research indicates
that they may be the closest relatives
to the seed plants. The fossil record
indicates that ferns originated during the Devonian period
about 350 million years ago and became abundant and varied
in form during the next 50 million years. Their apparent
ancestors had no broad leaves and were established on
land as much as 375 million years ago.

What are the 4 groups of plants?
The four main groups of plants are mosses, ferns, gymnosperms, and angiosperms. Mosses are non-vascular plants, ferns are seedless vascular plants, gymnosperms have naked seeds (like pine trees), and angiosperms have seeds enclosed in fruits (flowering plants).
What can you infer from the fact that seedless plants don't produce seed?
not
What are 2 seedless vascular plants?
Ferns are the most commonly known seedless vascular plant, while there are also horsetails and club mosses. Liverworts are not seedless vascular plants -- they are actually nonvascular.
What are the three phyla that are seedless and nonvascular?
The three phyla that are seedless and nonvascular are Bryophyta (mosses), Hepatophyta (liverworts), and Anthocerophyta (hornworts). These groups of plants rely on water for reproduction and lack specialized tissues for transporting water and nutrients.
List two ways that seedless vascular plants are important to the environment?
They denigrate, making good soil. Then other plants can grow there.
What are the three groups of seedless vascular plants?
Three groups of seedless vascular plants: Ferns, Mosses, Liverworts.
True or false the two large groups of plants are those that have leaves and those that do not have leaves?
False. Two large groups of plants could be seed plants and seedless plants, or vascular and nonvascular plants. All plants have leaves of some kind or another.

What are the two types of seedless plants?
The two main types of seedless plants are bryophytes and pteridophytes. Bryophytes, which include mosses, liverworts, and hornworts, are non-vascular plants that typically grow in moist environments. Pteridophytes, such as ferns and horsetails, are vascular plants that reproduce via spores and can often thrive in a variety of habitats. Both groups rely on water for reproduction and do not produce seeds.
What are the 2 main groups of vascular plants?
There is one division of angiosperms, Magnoliophyta, which is divided into two classes: monocots and dicots. Monocots are angiosperms with seeds having single cotyledons and dicots are the ones with seeds having two cotyledons.
Do seedless plants out number seed plants?
No, seed plants out number seedless by a lot.
In seedless plants what contains the eggs?
the spores all seedless plants have it.
What watermelons are seedless?
They are hybrid plants. Specifically grown to be seedless. I guess you could call them "engineered plants."
What are good questions to ask about Seedless plants?
Good questions to ask about Seedless Plants could include: - what are the differences between seedless and seeded plants? - Do seedless plants have better nutritional value than seeded plants? - Why do certain plants contain seeds?
